How To Allow Chrome To Access The Network In Your Firewall Or Antivirus Settings

Sometimes users experience issues with Chrome. If you are experiencing messages about the firewall or your antivirus software blocking applications you may need to change some settings to clear this problem. In this article, we cover how to allow Chrome to access the network in your firewall or antivirus settings.

What causes Chrome to be blocked?

A variety of software programs can interfere with Chrome’s operation.

Windows Firewall is the stock security-application included with Windows 10. Windows Firewall is intended to protect your computer by blocking any suspicious programs or harmful activity. You can adjust Windows Firewall’s settings to suit your security needs, but sometimes settings can be configured to incorrectly block harmless programs.

Windows Defender is the anti-malware software included with Windows 10, intended to block any malicious software and spyware. Windows Defender is a complete antivirus software that provides a robust free option, compared to other paid options. Windows Defender can also interfere with the regular operation of programs like Chrome.

Other antivirus programs that can cause the same problems include Avast, Malwarebytes, Bitdefender, McAfee, Kaspersky. Below is a set of instructions for solving connection issues with Google Chrome and the programs listed above.
